A woman in preterm labor at 30 weeks of gestation receives two 12 mg doses of betamethasone (Celestane) intramuscularly. The purpose of this pharmacologic treatment is to:
Reduce maternal and fetal tachycardia associated with terbutaline administration.
Suppress uterine contractions.
Stimulate fetal surfactant production.
Maintain adequate maternal respiratory effort and ventilation during magnesium sulfate therapy.
The Correct Answer is C
Betamethasone is a corticosteroid that enhances fetal lung maturity, which can help reduce the risk of respiratory distress syndrome and other complications in preterm infants. It does not reduce maternal and fetal tachycardia associated with terbutaline administration, suppress uterine contractions, or maintain maternal respiratory effort and ventilation during magnesium sulfate therapy.

Correct Answer is B
Explanation
Caput succedaneum is a common condition in newborns that causes swelling of the soft tissues of the scalp. It is usually caused by pressure on the baby's head during delivery and can be seen in both vaginal and instrumental births, such as vacuum-assisted deliveries. It generally crosses the suture lines, unlike a cephalohematoma.
Caput succedaneum is not a serious condition and generally resolves on its own within a few days without any treatment. However, the nurse should continue to monitor the newborn for signs of jaundice, which can occur due to the breakdown of red blood cells in the swelling.
Correct Answer is C
Explanation
A CS4 who has had three prior lower transverse cesarean sections is at the highest risk for uterine rupture.
